Stop Violating SOLID! The Interface Segregation Principle Explained in JavaScript
Writing clean, maintainable code starts with understanding the SOLID design principles — and the Interface Segregation Principle (ISP) might just be the simplest one to fix! 🚀
In this video, I’ll break down what the Interface Segregation Principle is, why it matters, and how to apply it using JavaScript — so you can stop forcing your classes to implement methods they’ll never use. Whether you’re building UI components, APIs, or enterprise systems, mastering ISP will instantly improve your architecture and code readability.
🔍 What You’ll Learn:
✅What the Interface Segregation Principle (ISP) means
✅How to identify “fat” or wrongly designed interfaces
